Problems solved by technology
However, due to the large amount of temperature-controlling gas used, when the temperature of the gas needs to be adjusted, the temperature of the gas cannot be quickly controlled to rise and fall. As a result, the temperature of the temperature-controlling gas entering the oven changes the temperature of the film surface slowly, and the energy consumption for heating and cooling is lost. rate is not high

Embodiment Construction
[0025] Such as figure 1 As shown, the present invention proposes a gas temperature control system of a polyimide film curing device. By presetting the temperature strategy for polyimide film curing, the temperature of the gas output from the temperature-controlled air mixer to the curing oven is controlled. In turn, the temperature of the gas blown out of the curing outlet in the curing oven can meet the requirements of the polyimide film curing temperature strategy, thereby achieving precise control of the polyimide film curing temperature, reducing energy loss during the curing process, and improving film curing. efficiency and quality.
[0026] In the embodiment of the present invention, the polyimide film curing device includes a curing oven and an air supply mechanism, and the air supply mechanism is used to supply air to the curing oven to cure the polyimide film.
[0027] The curing oven includes an air supply mechanism and a box body, and the air supply mechanism is a...

The invention discloses a gas temperature control system of a polyimide film curing device. The curing oven includes an air supply mechanism, and the curing air outlet at the front end of the air inlet channel outputs gas to blow and cure the polyimide film, and the cured waste gas passes through the The exhaust air inlet of the suction channel is sucked out; the air supply mechanism includes a temperature-controlled air mixer and a gas heater. The gas heater is connected to the temperature-controlled air mixer through the high-temperature gas interface. The air port is connected; the main controller controls the temperature of the gas output from the temperature-controlled air mixer to the air inlet channel according to the preset polyimide film curing temperature strategy, so that the temperature of the gas delivered to the curing air outlet meets the polyimide film curing temperature. Thin film curing temperature strategy requirements. In the present invention, the precise temperature control on the surface of the polyimide film is realized, the energy loss in the curing lifting process is reduced, and the efficiency and quality of film curing are improved.
Description
technical field [0001] The invention relates to the technical field of film curing temperature control, in particular to a gas temperature control system and method of a polyimide film curing device. Background technique [0002] The rapid development of flexible AMOLED display technology has made flexible display the most advanced technology in the consumer electronics industry. Consumer electronic products such as high-end mobile phones and watches all over the world use flexible AMOLED as their display screens. The core of flexible AMOLED lies in the use of polymer plastic substrates, which need to have the characteristics of high temperature resistance, corrosion resistance, dimensional stability, high mechanical strength, and easy coating. At present, only polyimide materials can meet the above requirements. The basic processing technology is to coat polyimide slurry on optical glass, and then solidify it into a film under nitrogen protection to make a flexible optical...
